Temperate Subantarctic Forests: A Huge Natural Laboratory
(Springer, 2021)In the southern tip of South America, temperate subantarctic forests develop on both sides of the Andes mountain range. Known in Argentina as Andean-Patagonian forests, these ecosystems cover a narrow but long latitudinal ... -
Temperature and day length drive local adaptation in the Patagonian foundation tree species Nothofagus pumilio
(BioRxiv, 2023-04-29)Climate change alters relationships among environmental conditions and thus has the potential to change the selection pressures acting on adaptive gene variants. Using a landscape genomic approach, we show that the southern ... -
Temperature and host plant species affect the performance and immunocompetence of an outbreak defoliator in northwestern Patagonia
(Royal Entomological Society, 2022-03)1. Rising temperature has been associated with increased occurrence of herbivorous insect outbreaks, explained by several direct and indirect mechanisms. Whereas natural enemies are known key drivers of forest-defoliating ... -
